as of February 8, 2023

Installation instructions:

    1. Click on 'Download' and choose to save the file to your computer. Select an easy place to find the file, such as the 'My Documents', 'Downloads', or 'Desktop'.
    2. Once the download is complete, double-click to open the zip file from the location it was downloaded to.
    3. Drag the 'Garmin' folder from this location and drop it onto the card. The 'Garmin' folder should be the highest level folder on the SD card.
    4. Power on the device and make sure all attached network devices are powered on as well.
    5. Insert the card into the card slot of your primary device. Select 'Update Software' in the window that automatically displays. If you do not have a primary device with a card slot, please see your dealer or attempt to use the ActiveCaptain app to update software.
    6. After the update completes, all Garmin Marine Network devices and NMEA 2000 sensors will have the latest software. This ensures all of the devices will be able to communicate with each other.

    Note: If you have additional chartplotters connected to NMEA 2000 and not the Garmin Marine Network, you will have to independently update each chartplotter. After the update of the Garmin Marine Network completes, insert the update card into each NMEA 2000 chartplotter.
